Height-adjustable golf tee system

Abstract

An adjustable height golf tee system having a tee and an anchor is discussed. The tee is height-adjustable relative to the anchor. A first anchor includes a cap, a stem, and a tip. The stem can be threaded internally, externally, or a combination thereof. A second anchor includes a base, a first stem, a cap, and a second stem as well as optional spacers. The stems can be threaded internally. Both the first and second anchors can be composed multiple pieces (e.g., a detachable cap, a detachable stem, or a detachable portion thereof) to provide access to an inner cavity of the respective stems.

What is claimed is: 
     
       1. A golf tee anchor system comprising:
 an anchor comprising:
 a tip formed by a first end of the anchor, 
 a cavity disposed between the first end of the anchor and a second end of the anchor, the cavity at least partially defined by one or more inner walls of the anchor, the cavity defining a first portion and a second portion, the one or more inner walls of the anchor defining the first portion of the cavity defining a plurality of threads, having a maximum diameter, and 
 a curved or tapered opening at the second end of the anchor, the curved or tapered opening having a diameter larger than the maximum diameter of the plurality of threads, the curved or tapered opening configured to permit a broken or sheared tee to be removed from the cavity; and 
 a tee comprising: 
 a shaft having a first end and a second end, the second end of the shaft configured to be inserted into the cavity of the anchor, and 
 a head disposed at the first end of the shaft, the head configured to extend out of the curved or tapered opening of the cavity and to support a golf ball. 
 
 
     
     
       2. The golf tee anchor system of  claim 1 , wherein a length of the tee extending out of the cavity is adjustable. 
     
     
       3. The golf tee anchor system of  claim 1 , further comprising a first cap at the first end of the anchor, the first cap integral with the anchor. 
     
     
       4. The golf tee anchor system of  claim 3 , further comprising a second removable cap configured to be positioned over the first cap. 
     
     
       5. The golf tee anchor system of  claim 1 , wherein an outer surface of the anchor comprises threads. 
     
     
       6. The golf tee anchor system of  claim 1 , wherein the tip comprises a pointed end. 
     
     
       7. The golf tee anchor system of  claim 6 , wherein the cavity is at least partially defined by inner walls of the pointed end of the tip. 
     
     
       8. The golf tee anchor system of  claim 1 , wherein the tee is removable from the anchor. 
     
     
       9. The golf tee anchor system of  claim 1 , wherein the second end of the anchor further comprises a slot extending generally perpendicular to a longitudinal axis of the anchor, the slot configured to receive a tool for inserting the anchor into a surface. 
     
     
       10. The golf tee anchor system of  claim 1 , wherein the shaft of the tee comprises threads configured to interact with the threads of the cavity.
